Geikie's Geological Map of Scotland

Abstract

SINCE the publication of the last edition of the sketch-map by Sir R. I. Murchison and Prof. Geikie, no general geological map of Scotland has, so far as we are aware, been issued, while those older than the sketch-map rather served as guides to localities where minerals and rocks were to be found, than afforded any clue to the subdivisions of geological time represented by our ancient formations. During the last twelve years, however, materials have been accumulating which have daily rendered the sketch-map more and more inadequate to the purposes for which it was originally designed, and it had obviously become necessary either to issue a new edition, or to “reform it altogether.” Considering all things, and especially that he could no longer avail himself of the cooperation of his late colleague, Prof. Geikie has, wisely we think, decided on the latter course. The comparatively large scale adopted (ten miles to the inch), gives room for a number of details which had to be omitted from previous maps.
